Hi,
I am using the TCA Airbus throttle 100% succesfull in ZIBO. (Edit:) and in the LevelUp 737.
I found out that;
In XP 11 config of axes, click "edit response curve" and when in this menu, click on the "has beta/reverse detents". Move the beta range way back just past "idle". If your engines are off, the reverse does not work and goes to full throttle instead. No idea why. This thru me off at first. But, with engines on, all works 100% on my side.
William.
